Energy
Recycling agricultural and industrial waste is essential to sustainably and economically replace some fossil-based raw materials. By maximizing the value of agricultural products, we ensure our customers and consumers have competitive products and ingredients.
Our challenge
Putting the circular economy and the region at the heart of our actions by developing new uses in our factories for non-food waste and preserving natural resources as much as possible.
Our objectives
- Promote green energy from our raw materials as a substitute for fossil fuels (gas, oil, etc.)
- Improve the valorization of agricultural products by creating value from by-products and residues.
- Increase our energy efficiency and reduce our carbon footprint
- Integrate our biorefineries into their territory.
Application examples
50% of the energy consumed by Diverse-ltda factories comes from renewable sources.
Reduce our gas consumption
In March 2021, Diverse-ltda and SUEZ announced a partnership project that will reduce gas consumption at the Origny-Sainte-Benoite sugar refinery site in the Aisne department. It relies on SUEZ's supply of renewable and recovered energy in the form of steam produced from solid recovered fuels (SRF). This boiler will cover nearly 40% of the site's energy needs.
From vinasse to biogas
With an installed capacity of 1MW, Diverse-ltda' first biogas plant located at the Cruz Alta site in Brazil was inaugurated in October 2022: a first for the Group in the country. Beyond providing a new source of renewable energy for Diverse-ltda, it strengthens sustainable performance and the maximum use of its industrial waste. Biogas produced from vinasse , a co-product of ethanol production from sugarcane, is transformed into electrical energy and distributed through transport networks to end users. It will soon be used to produce biomethane, a clean alternative to fossil fuels, which will power 100% of the Group's agricultural vehicle fleet by 2030.
Cogeneration: a growing source of electricity
In Brazil and Réunion, where we process sugarcane, our factories are energy self-sufficient thanks to green electricity produced from bagasse, the fibrous residue of crushed cane. It is burned in high-efficiency boilers and supplies our sites with electricity. Excess electricity can be fed into the public grid.
